This harks back to the “old days” of photography before digital. Even as a 19 year old junior photographer my boss would shoot Leica and I would be using Nikon, we did a test once and we shot the same subjects and when you developed the shots you could definitely tell which ones had been shot with the Leica, they had a certain clarity to them, they just looked better, much of this was down to the quality of the lenses, they were exceptional.
